I have determined the driver version for my 32bit Dell Dimension E520 using the intel driver utility. I have also tried the dell website which does not have the correct driver. I downloaded and tried to install: win7_1512754. I have tried several methods: the standard update driver option through the device manager; installing the driver using the .exe; installing the driver then rebooting then hitting update; also tried locating the driver that I downloaded but it can’t locate the exe.

Essentially I need a way to overwrite the existing driver with the new driver by forcing it to use the new version.
